SPECIFICATION forming part of Letters Patent No. 715,888, dated December16, 1902.

Application filed May 5, 1902. Serial No. 106,974. (No model-3 T0 onwhom, it may concern:

Be it known that I, SETH SMITH, residing at Castana, in the county ofMonona and State of Iowa, have invented certain useful Improvements inOne-Horse Cultivators; and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to a new and novel improvement in one-horsecultivators.

The aim of my invention is to provide an articulated cultivator soconstructed that the cultivator-beams, to which the cultivatorshovelsare secured, are normally held by the operator, so that the shovels maybe spread inward or outward.

The object of my invention is to provide a cultivator comprising a head,to which are articulated the cultivator-beams, which are held at therear end by the operator, so that the cultivator-shovels are held underadjustment by the operator and may be carried inward or outward in sucha manner that the cultivator shovels may be carried against any weeds orvegetation to remove the same or be carried sidewise to escape anobstructionas a stone or stump, for instance.

In the accompanying drawings Ihave shown in Figure 1 a top view of acultivator embodying my invention. Fig. 2 shows a detail of thecarrying-head, while Fig. 3 shows a side view of my invention. 7

In carrying out the aim of my invention I provide a carrying-headcomprising the upper fiat plate B, the lower counterpart plate B, whichplates are connected in front by means of the vertical pin C and uponthe rear by means of the two vertical pins b, as is shown in Figs. 1 and2. This forward pin 0 is provided with the sheaves c, as is shown inFig. 2. the upper plate B are the ears D, provided with the horizontalpins 9, as shown. EX-

tend upward from the lower rear portion of the lower plate B is theholder H, suitably perforated to receive a pin 15, and this holderadjustably secures the trailing knife I, pro

Depending from the forward end of vided with a guard 1, extendinglaterally upon one or both sides to prevent this knife cutting too deepinto the earth. This trailing knife is in the form of a support orrunner and holds the carrying-head. To this lower plate B may further besecured a suitable shovel. Loosely articulated to the rear pins b arethe two angular cultivator-beams A and A, the forward ends Ct of whichare adapted to work into the carrying-head and are provided withsuitable perforations in front, as is shown in Fig. 1, to receive thepins 13 and 14, to which are secured a suitable strand F, which strandworks over the sheaves c, secured to the center pins 0, being looped infront to receive a hook 10, by means of whichthe cultivator is draggedthrough the field. The trailing knife I is provided with the lateralextension f, which holds the 'knife in position, as disclosed in Fig. 2.To the rearward portion of these pivotally held and articulatedcultivator-beams A and A are a plurality of suitable shovels 2, and atthe rear, by means of the pins 3, are secured the handles 4 and 4', heldby means of the braces 6 and 6, secured by the bolts 5 and 5 7 and 7.

A single draft-animal is secured to this cultivator by means of asingletree 13, secured to the hook 10 by means of the chain 12, so thatthe cultivator may be drawn through the field.

In using this cultivator should the operator encounter a weed uponeither one side or the other he can swing the cultivator-beam upon thatside inward or outward to engage and remove it. So,also, should a stumpor a stone be encountered the beams may be laterally shifted to escapethe same.

other or away from one another or be operated independently. In Fig. 1they are shown distended their fullest capacity. When the draft-animaldraws upon the strand F, the forward ends a and a of thecultivator-beams are carried toward one another. To counteract thisstrain, the operator grasps the handles 4 at and carries them toward oneanother a suitable distance, so that these cultivatorbeams can always bethrown outward a sufficient distance within the furrow to properlycultivate the same.

Both the cultivator-beams may be carried toward one an- If desired, awheel could be secured to the trailing knife I, so that the cultivatorbe carried to or from the field as a wheelbarrow would, for instance.

lhe device is simple of construction and readily operated, and

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

1. The combination with a suitable head, of a pin vertically positionedwithin said head, two angular cultivator-beams pivoted near one end toaforesaid head, a strand passing from the forward end of one of saidcultivator-beams and looping about aforesaid pin and being secured tothe remaining cultivator-beam as set forth, a singletree secured to theloop of aforesaid strand, a plurality of SETH SMITH.
